Description martin.strecker 2017-08-23 15:54:37 UTC 
Application: plasmashell (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.79-18.26-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:

I had an external monitor connected to my laptop. When disconnecting the external monitor (selecting the corresponding display in the Display and monitor configuration window, unselecting the "enabled" button, then withdrawing the external monitor cable), Plasma crashed, but then came back and displayed the desktop contents correctly.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
